Sigh v. i. [imp. & p. p. {Sighed}; p. pr. & vb. n. {Sighing}.]
1. To inhale a larger quantity of air than usual,
and immediately expel it; to make a deep single
audible respiration, especially as the result or
involuntary expression of fatigue, exhaustion,
grief, sorrow, or the like.
[1913 Webster]

Description:
A home monitoring system that measures and 'collects' sighs. The result is a physical visualization of the amount of sighing, for personal use in a domestic environment.

The project is in two parts. The first part is a stationary unit, which inflates a large red air bladder upon receiving the appropriate signal. The second part is a mobile unit, worn by the user, which monitors breathing (via a chest strap) and communicates a signal to the stationary unit wirelessly when a sigh is detected.
